The original Sea Quartz spirit, in a refined 38mm case

For years, the Sea Quartz 30 has been one of our most recognizable watches: bold, legible, tough, and unmistakably inspired by the golden age of professional dive watches.

The new Sea Quartz 30 Heritage 38 keeps that same vintage Sea Quartz character, but brings it into a more compact, easy-wearing 38mm case size. It was created for customers who love the look of the original 42mm model, but want a watch that sits more naturally on smaller wrists — or simply prefer the balanced proportions of a classic mid-size diver.

This is not a scaled-down afterthought. The Heritage 38 was designed to preserve the details that make the Sea Quartz 30 distinctive: the broad cushion-style case, protected crown, highly legible dial, bold luminous markers, orange minute hand, day-date display, rotating dive bezel, and reliable Swiss quartz movement.

The result is a watch that feels familiar the moment you see it, but wears with a new level of comfort and refinement.

Vintage proportions. Modern capability.

The Heritage 38 takes its cues from the era when dive watches were built as tools first — compact, clear, and dependable. At 38mm, the case has a more traditional fit than many modern divers, making it ideal for daily wear, travel, and active use.

It slips under a cuff more easily, feels less bulky on the wrist, and delivers the same confident Sea Quartz presence without overpowering the wearer.

Inside is a dependable Swiss quartz day-date movement, chosen for accuracy, durability, and low-maintenance ownership. Outside, the Heritage 38 is built to do what a Sea Quartz should: handle real use, not just look the part.

Made for wrists that wanted the original — only smaller.

Many customers have asked us for a Sea Quartz 30 with the same design language as the original, but in a case size better suited to slimmer wrists. The Heritage 38 answers that request directly.

It keeps the character.
It keeps the toughness.
It keeps the legibility.
It simply wears smaller, cleaner, and more comfortably.

Inspired by the Original Magnum P.I. Watch

In the early 1980s, CBS launched Magnum, P.I., starring Tom Selleck and set against the iconic backdrop of Hawaii. The series became one of the era’s biggest television hits — and during the first three seasons, Selleck wore the original Chronosport Sea Quartz 30. The Sea Quartz 30 Heritage 38 carries that legacy forward. Inspired by the original Sea Quartz 30, it brings the same unmistakable dive-watch character into a refined 38mm case. From its bold, highly legible dial and signature orange minute hand to its rugged, purpose-built design, the Heritage 38 stays true to the spirit of the watch that helped make the Sea Quartz an icon — now in a more compact, classic size.
